High-efficiency liquid-scintillation counting of 14C-labelled material in aqueous solution and determination of specific activity of labelled proteins.
1. Inexpensive scintillation mixtures are described which enable the detection of as little as 40mumuc of (14)C in aqueous solution with an efficiency of counting of over 80%. 2. A rapid method for the counting of alkaline, acidic and neutral aqueous solutions of up to 1ml. volume is described. Ethanol or 2-ethoxyethanol is used as blending agent. 3. The scintillation counting of alkaline solut...
متن کاملOptimization Method to Determine Gross Alpha-Beta in Water Samples Using Liquid Scintillation Counter
Liquid scintillation counting (LSC) is an adequate nuclear technique to determine radioactivity levels, as verified by this study for the determination of the gross alpha and beta activities of aqueous samples because of its simplicity and low associated cost comparison with other techniques. This paper discusses a new approach to the monitoring of gross alpha and gross beta activities in water...
متن کاملCocktails for Liquid Scintillation Counting
It is most important to assure 4 π−geometry in liquid scintillation counting for accurate results1. Usually this can be assured by dissolution of the sample in an appropriate cocktail. The cocktail does not only contain a solvent but also at least one scintillator and surfactants for aqueous samples because aqueous samples are completely insoluble in the pure organic solvents and scintillators....
متن کاملThe Effect of Quench on Quantitating Alpha Radionuclides by Liquid Scintillation Counting
Detecting and quantitating alpha emitting radionuclides are routine tasks in nuclear energy and environmental monitoring. For this purpose, liquid scintillation counting (LSC) is an excellent method because alphas are counted with nearly 100% counting efficiency with low backgrounds, even with severe quenching. Quenching agents such as inorganic acids, organic acids, and extractive scintillator...
